Looking forward to see this feature!

[PrisionMike]

Will be closed after #6524 is merged. Remaining issues will be dealt with individually

[PrisionMike]

• SignMessageV2 will not be supported for now.
• Remaining items have issues assigned to them, under which they will be addressed. Thus marking them as done and closing the issue.
